Warmer temperatures, from global warming and from incredibly low soil moisture levels, are also likely to prolong the drought itself, according to several recent studies.
The mega-heatwaves began in a similar manner, with one key difference: each started over areas with low soil moisture.

At a global scale, increased CO2 concentrations could partially offset expected yield declines caused by lower soil moisture and higher temperature, but recent models suggest a significantly smaller fertilization effect from CO2 than previously predicted (25).
Blue depicts areas with higher soil moisture than usual, while brown shows lower soil moisture than usual for this time of the year.

Not exact matches

Shaded microsite areas found below mature pinyon pine canopies (or overstory) have lower soil temperature and retain higher soil moisture content, both of which are fundamental to new tree regeneration.
According to Greg Okin, a professor of geography at the University of California, Los Angeles, «Climate models predict that the Southwest should get warmer and drier, and that by 2050 soil moisture could be lower than the US Dust Bowl Era.»
Although soil moisture and warming were the more significant factors that led to early ripening, the low yields from wine - grower practices also played a part.
A new study in Nature Climate Change finds that warming and declines in soil moisture, but also vine management practices to lower yields to produce better - quality grapes, brought the fruit to early maturity.
«By 2050 soil moisture could be lower than it was in the Dust Bowl era.»
The combination of higher evaporation and lower precipitation depletes soil moisture and reduces runoff, making droughts more intense and more frequent.
Rather than focusing just on lower rainfall, the team measured three types of drought as they affect Jordan: rainfall decrease, agricultural soil moisture loss and declines in freshwater streams.
Analyses showed that high - frequency irrigation resulted in higher root zone soil moisture content relative to low - frequency irrigation despite reduced evaporative demand during part of the growing season.
But even under ideal temperature and moisture conditions, productivity gains will be dependent on local site conditions, such as where there are sufficient soil nutrients or where stand density is low and little competition exists for available resources (Ford et al. 2016).
HELEN FRANKENTHALER (B. 1928) Pranzo Italiano (Harrison 44) etching and aquatint in colors, 1973, on White Fabriano, signed and dated in pencil, numbered 34/43 (there were also 3 artist's proofs), published by 2RC Edizioni d'Arte, Rome, with full margins, two pale foxmarks in the lower margin, moisture staining at the lower sheet edge (associated pale foxing, primarily visible on the reverse), occasional pale surface soiling in the margins, otherwise in good condition P. 8 1/2 x 7 7/8 in.
«Inconsistent signal in consecutive dry days and soil moisture changes,» to which they assign a low confidence.
Methods such as accurate water measurement and soil moisture monitoring, laser - leveling fields, using conservation tillage to retain soil moisture, switching to low energy precision application sprinklers, lining canals, and employing subsurface drip irrigation where possible could save upwards of 40 percent of agriculture's water use while improving crop yields and saving energy.
But the IPCC report had low confidence in projected changes to soil moisture, one of the main indicators of drought.
Until you can all agree on whether changes in soil moisture are due to lower solar, or due to higher CO2, use solely sea surface temperatures for global mean surface T change.
Soil moisture remained good in the Lower Valley due to their wetter than normal season but in the northern parts of Texas, soil moisture is declining (Information provided by the Texas Office of State ClimatoloSoil moisture remained good in the Lower Valley due to their wetter than normal season but in the northern parts of Texas, soil moisture is declining (Information provided by the Texas Office of State Climatolosoil moisture is declining (Information provided by the Texas Office of State Climatology).
Researchers in the historical Beaver Creek experiments hypothesized that lower tree densities associated with thinning would reduce evapotranspiration losses, and thereby allow more water to be available for soil moisture, groundwater recharge, and surface water runoff [29].
The darker grey shading denotes where soil moisture is not shown due to ice cover or climatologically low precipitation.
Commercial SSO waste streams are likely to contain a high proportion of soiled paper waste compared to food waste; however, on a weight basis it would be expected that the fraction of food waste is higher due to the fact that food waste is very high in moisture, whereas paper material would be much less dense with a lower moisture content.
Wherever a forest is converted to a grassland, or a grassland to desert, or barren ground is created, maximum skin surface temperatures rise by 10 to 40 °F.8 Also to quench the thirst of growing populations, extraction of subsurface waters has lowered the water table.9 As the water table drops below the reach of roots, soil moisture is reduced and plants die.
As a result, the peaks in California's snow melt and surface runoff are likely to be more pronounced and to occur earlier in the calendar year, increasing the duration of the warm - season low - runoff period and potentially reducing surface soil moisture.
Unresolved issues that will be addressed in a series of forthcoming studies include the effects of ocean dynamics on the predictability of low - frequency atmosphere and land variability and the feedback of soil moisture variations on atmospheric temperatures and circulation (e.g., Rowntree and Bolton 1983; Atlas et al. 1993; Koster et al. 2000).
From the Southwest to the Great Lakes, temperatures have been so high and rainfall so low that the drying effect of warmer air temperatures far exceeded what little precipitation there's been, resulting in moisture being drawn out of soils.
The loss of the low - frequency channels, particularly at 6.9 GHz, would mainly impact the measurement of SST and soil moisture, although it also would degrade the accuracy of some other retrievals such as measurements of wind speed.
